9655ad03af sh: Fixup machvec support.
This fixes up much of the machvec handling, allowing for it to be
overloaded on boot. Making practical use of this still requires
some Kconfig munging, however.

7a302a9674 sh: Split out CPU topology initialization.
Split out the CPU topology initialization to a separate file,
and switch it to a percpu type, rather than an NR_CPUS array.

At the same time, switch to only registering present CPUs,
rather than using the possible CPU map.

f413d0d9fa sh: Use a jump call table for debug trap handlers.
This rips out most of the needlessly complicated sh_bios and kgdb
trap handling, and forces it all through a common fast dispatch path.
As more debug traps are inserted, it's important to keep them in sync
for all of the parts, not just SH-3/4.

As the SH-2 parts are unable to do traps in the >= 0x40 range, we
restrict the debug traps to the 0x30-0x3f range on all parts, and
also bump the kgdb breakpoint trap down in to this range (from 0xff
to 0x3c) so it's possible to use for nommu.

Optionally, this table can be padded out to catch spurious traps for
SH-3/4, but we don't do that yet..

This implements initial support for the SH7206 (SH-2A) and SH7619
(SH-2) MMU-less CPUs.

19f9a34f87 sh: Initial vsyscall page support.
This implements initial support for the vsyscall page on SH.
At the moment we leave it configurable due to having nommu
to support from the same code base. We hook it up for the
signal trampoline return at present, with more to be added
later, once uClibc catches up.

3aa770e797 sh: APM/PM support.
This adds some simple PM stubs and the basic APM interfaces,
primarily for use by hp6xx, where the existing userland
expects it.

1c5f8f85df sh: Move syscall table in to syscall.S.
Move the syscall table in to its own file, as per sh64. The entry.S
bits will end up being considerably different in the sh2/sh2a cases,
so this lets us keep things in sync somewhat..

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
